The Sanitary Sewer System

Dont Flush These Items

The Sanitary sewer system of the Municipality of Bethel Park is comprised of over 200 miles of sewer system of varying sizes, with the majority being 8” vitrified clay pipe and over 6000 sanitary manholes.  The Bethel Park sewer system is a separate system, meaning it is only meant to convey waste water, i.e. toilet, shower, laundry and not storm water.  It is important that sump pumps, downspouts, french drains, or any other systems collecting storm water do not connect to the sanitary system.

The system is divided into two major sewer sheds with approximately 2/3 of the sewer system draining to the Bethel Park Waste Water Treatment Facility, located in South Park, and the remaining 1/3 drainage to ALCOSAN (Allegheny County Sanitary Authority).  These two water sheds are then delineated into nine smaller subsheds corresponding to their drainage area.

Each year the Municipality of Bethel Park budgets for projects that are developed to mitigate potential malfunctions within the system.  Projects consist of internal and external repairs.
